Feel Wellcome
Go to Euston (Northern or Victoria line) or Euston Square (Metropolitan, Circle, Hammersmith lines) and it’s a very short walk to the Wellcome institute.
There’s always something interesting to see, and it’s not overwhelming.
While we are highlighting the smaller, less overrun and approachable museums and galleries, let’s also mention the Imperial War Museum (Lambeth North) and the Wallace Collection (Oxford Circus).
